CONCERNING...SEVERE THUNDERSTORM WATCH 721...

VALID 142244Z - 142345Z

...STRONG THUNDERSTORMS WILL CONTINUE FOR THE NEXT SEVERAL HOURS
ACROSS WW721...

STRONG BOUNDARY LAYER INSTABILITY HAS YET TO BE OVERTURNED ACROSS
PORTIONS OF THE MID MS AND LOWER OH VALLEY REGION.  LATEST
DIAGNOSTIC DATA SUGGESTS AN AXIS OF 2500-3500 J/KG MLCAPE EXTENDS
FROM NERN AR...INTO WRN KY.  MULTIPLE STORM MERGERS WITH A SLOW
EVOLUTION INTO LINE SEGMENTS WILL BE COMMON THROUGH SUNSET.  STORM
MOTIONS ARE MODEST AT BEST AND ACTIVITY WILL LIKELY LOSE ITS
INTENSITY WITH LOSS OF HEATING BEFORE ACTUALLY PROGRESSING
COMPLETELY SOUTHEAST OF THE WATCH.  LOCALLY STRONG WINDS APPEAR TO
BE THE MAIN THREAT WITH ORGANIZED LINE SEGMENTS.
